DOOR-HAN GER.

Application filed June 6. 1918.

To all whom it may concern Be it'know'n that I, JULIAN E. CORBIN, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Door-Hangers, of which the following is 'a specification.

This invention relates to improvements in hangers and more particularly to a device for mounting sliding doors, windows and like closures. 1

The principal'objects of the invention are to provide a device which'permits the easy operation of the closure, which is simple in construction and which isnoiseless in operation.

With these and other objects in view, the invention consists of'certain novel features of construction, combinations and arrangements of parts hereinafter described and more specifically pointed out in the appended claims; it being understood that changes in form, proportion, size and minor details of construction within the scope of the,

claims may be resorted to without departing from the spirit of the invention or sacrificing any ofthe advantages thereof.

Referring to the drawings forming a part of the specification,

Figure 1, is a view in side elevation showing a door in its closed position and the manner in which my improved hanger is attached thereto.

Fig. 2, is a corresponding view of the door partly opened.

Fig. 3, is a view 1 in end elevation.

Fig. 4, is an enlarged sectional view on the line 44, Fig. 1. Fig. 5, [is a view in modified form of my invention.

Referring tofcorresponding parts in the several views by the same numerals of reference, 1 denotes a door or otherhorizontally movable closure which is adapted to move across the opening 30, and into a pocket formed on one side thereof. Above this opening is a longitudinal recess 31 on the sides of which are the supporting members 2. Attached to the adjacent faces of these members are a pair. of parallel rails to which are pivotally attached certain link members hereinafter described. These rails may be of any preferred form and attached to the supporting structure in the most convenient manner.

Likewise the hanger is attached to the door in any preferred way which may vary Specification of Letters Patent.

with difi'erent conditions. As here illustrated, to the top edge of the door is attached a longitudinal strip 5 to each side of which are clamped rails 4 which are higher than strip 5 thus forming a slot in which various links hereinafter mentioned are p0- sitioned; The strip 5 is attached to the top of the door by screws 6 and the rails 4 to strip 5 by screws 7 Pivotally attached to the rails 3 and 4 is a'pair of links Sand 12 each of the same length and having their other ends pivotally attached to each other and to a'bar 10 as shown at 32. A similar pair of links 9 and 13 have their lower ends pivotally connected to the rails 3 and 4, respectively, and their outer ends to each other, and to the other end of bar 10 as at 33. The length of bar 10 is equal to the distance betweenthe lower pivotal points of the parallel links 8-9 or 12-13. The links 8 and 9 are preferably formed of two parts with the lower ends connected to the opposite rails 3.

Pivotally attached to the rails 3 and 4, respectively, is a third pair of links 14 and 15 whichare of equal length and disposed so that angular relation between them is always different from the angular relation between the pair 812 or 913. These links 14 and 15 are placed between the aforesaid mentioned pair in order to economize in length and they have their outer ends pivotally attached as at 34. The length of these two members is such that when the door with the attached members 4 moves in a horizontal direction, the axis of the pivot 34 will describe substantially an arc of a circle.

On the pivot 32 which joins the links 8, 12 and the bar 10, is mounted a connecting member 16 and on the pivot 34 to which the links 14 and 15'are attached is mounted a shorter connecting member 17 the outer end of which is pivotally connected to the outer end of member16 as at 36. The length of these two members is such that when the doorwith the attached members 4 moves in a horizontal direction, the :axis of the pivot 36 will describe substantially an arc of a circle.

On the pivot 36 are also mounted links 21 the length of which is that of the radius of the are just mentioned and which have their lower ends pivotally attached to the member 3 at the center of this arc. Thus by causing the pivot point 36, by means of Patented May 13, 1919.

links 21, to move in the are which it describes when the door is moved horizontally, the latter will move horizontally when the hanger is operated. It will be noted that when the angle between the links 1l 15 is obtuse, the links 812 and 9-21 are at an acute angle.

then the links I l-15 will be at a lesser angle. This construction enables me to obtain the greatest practical movement of the door for a given length of levers as in no case are" all the links so flattened out that excessive strain is produced in the parts.

The door itself, is" maintained in a horizontal position by means of the parallel levers 9 and 13, 8 and 12 and by the further pair of levers l l and 15. Thus when the door is moved toward the left the various 1evers assume the position shown in Fig. Qand to all intents and purposes the door moves in a horizontal direction. In this construction but little head room isrequired in order to gain a large door openingand the latter will move quietly and easily. and there areno parts to become out of orderv or'rollersto jump out of their cooperating track or grooves. The weight of the. door is uniformly distributed over a number of piv otal bearings which therefore do not readily become out of order.

As the links which constitute the pairs 812, 913' and L t-15 are of equal length and the lower pivotal points are in the-same plane it will be'apparent that each of these pairs always form an isosceles triangle and that the pivotal points 82:33 and 34 will move half the distance that the door travels and therefore each moves the same horizon,- tal, distance, Hence, the links 1617 21 constrain the points 32'84 to move equal distances for a given horizontal movement of the door and maintain the required relation between the pairs of links that the latter will support the door and cause itto move in a horizontal direction.

Furthermore by locating the lowerpivotal point of link 21 out of the center Of the, are above described, the door canbe made to slightly rise or fall toward the. end of its travel to the lift and can therefore be made self-closing or self-opening.

In the modified form shown in Fig. 5 instead of providing a pair of parallel connected links to prevent a pendulum-like movement of the door, I provide two independent sets of' links arranged one adjacent each side of the door. In this arrangement, links 50 and 54:, corresponding to links 12 and 15 of the main form, are pivotally ate tachedto the door while links 52, 53 and 55 corresponding tolinks 8, 14 and 21, respece tively, have their lower ends attached to frame 51. Links 50 and 5 2 have their upper On the other hand, when the. door is moved a sufficient distance. to make an obtuse angle between the llnks 8-12,

ends pivotally connected to each other and to theconnecting link 56. Links 53 and 54 have their upper ends pivotally connected to each other and to the short link 57, while the other end of links 55, 56 and 5-7 are pivotally connected at a common point.

While 1* have shown and described thepreferred embodiments of my invention, it will be understood that I do not confine myself to these arrangementsbut Wi$h to, cover such modific t ns at embra ed. i h the cop of. theq aims. I
